摘要:
To a logic circuit model, a test pattern by a combination of a first logical value A representing 0 or 1 and a second logical value B representing 1 or 0 as an inverse value corresponding to the first logical value A is given to calculate an output of the logic circuit model with a logical operation and, when the output is compared with an expected value for the test pattern and they are equal to each other, it is determined that the operation of the logic circuit model is correct. With the second logical value B representing 1 when the first logical value represents 0 and the second logical value B representing 0 when the first logical value A represents 1, a logical operation of the logic circuit model is performed.

A transmission illumination apparatus for a microscope has an optically transparent sample mount plate on which a sample is mounted, a surface light source that projects substantially uniform illumination light toward the sample mount plate, and a light orientation member that restricts diffusion of the illumination light in relation to at least one direction.

When a simulation model generation unit converts logic on the gate level into a basic primitive which can be executed by a simulator to generate a simulation model, for the basic primitives a degeneracy processing unit determines and deletes a gate which can be deleted and which will not affect the delay stage count. The degeneracy processing unit is provided with a constant gate degeneracy unit which puts a plurality of constant gates together, a buffer degeneracy unit which deletes fan-out-free buffers and an identical fan-in gate degeneracy unit which puts identical fan-in gates together.

A microscope includes a microscope main unit including a stage on which a specimen is to be placed; and a light source provided on the microscope main unit and emitting illumination light for illuminating the specimen. The microscope also includes a main power supply operable to be turned on and off; a sensor that senses the presence or absence of a subject in a front or side area of the microscope main unit; a determining unit that determines based on a result of the sensing whether the subject moves; and a control unit that turns on the light source when the main power supply is turned on, maintains the light source in an ON state when the determining unit determines that the subject moves, and turns off the light source when the determining unit determines that the subject does not move and a predetermined period of time passes.

An image pickup apparatus has an image sensor recording image information; a dustproof glass for keeping hermeticity of the periphery of the image sensor, placed in front of the image sensor; an optical filter removably placed in front of the dustproof glass; and a camera mount placed in front of the optical filter. The image pickup apparatus further has a parfocal adjusting device in which a focal position where the optical filter is demounted can be adjusted so as to be nearly equal to the focal position where the optical filter is mounted.

An exhaust-gas muffler includes a casing and a relief valve. The relief valve is provided to open when a pressure of an upstream exhaust-gas chamber is equal to or higher than a predetermined value. The relief valve includes a shutter, a spring, and a seal member. The shutter member is provided to face an open end of a gas passage provided between an upstream exhaust-gas chamber and a downstream exhaust-gas chamber. The spring is to bias the shutter member in a direction in which the gas passage is closed. The seal member is disposed on a downstream side of the gas passage. The seal member is made of a metal mesh material and has a disc shape to cover the open end of the gas passage.
